Cylinder Head 107 - 4G63 HLA Lifter Tech

I have all 3 revisions of the DSM lifters in this video. This will help you identify which ones are in your cylinder head, as well as illustrate the cleaning process, and each lifters' advantages and disadvantages.

WHEN you finally have to perform maintenance on these lifters, they're a bigger pain than a solid lift valvetrain is (ONCE). BUT if you follow the service schedule on a solid lift valvetrain, HLA's are a smaller pain overall.

You'll never need feeler gauges to adjust these hydraulic lifters, and you'll never need to know their gap. You can't adjust them. You'll just know whether or not they're good by the amount of noise they make. 3 things can cause trouble with them. Clogged lifters, insufficient oil pressure, or insufficient oil volume.

So before you sail your oil pump down the river, you can follow the steps in this video to rule out the first variable. You can actually remove and re-install them without taking the timing belt or camshafts out, but that will be another video. Chances are you already know this. The second and third potential issues COULD be your oil pump, but for your oil light isn't on and if there's ever been machine work in its past history to either the head or the block, I explain in "Cylinder Head 103 - Deck Tech" what a frequently-overlooked part of the cylinder head is that could be a contributor to the issue. That link is in the video.

I MENTIONED ANOTHER COOL VIDEO: it was here...

Thank that author as well. He did a great job! I don't know the guy and claim no credit to his work, I'm just giving him a shout-out.
